審核 。碳鋼無縫鋼管是一種具有的長條鋼材。鋼管具有中空截面，大量用作輸送流體的管道，如輸送石油、天然氣、煤氣、水及某些固體物料的管道等。鋼管與圓鋼等實(shí)心鋼材相比，在抗彎抗扭強(qiáng)度相同的同時,重量較輕，是一種經(jīng)濟(jì)截面鋼材，廣泛用于制造結(jié)構(gòu)件和機(jī)械零件，如石油鉆桿、汽車傳動軸、自行車架以及建筑施工中用的鋼腳手架等。中文名外文名Carbon

時，如滾動軸承套圈、千斤頂套等，當(dāng)前已廣泛用鋼管來制造。鋼管還是各種常規(guī)武器不可缺少的材料，槍管、 炮筒等都要鋼管來制造。鋼管按橫截面積形狀的不同可分為圓管和異型管。由于在周長相等的條件下，圓面 積最大，用圓形管可以輸送更多的流體。此外，圓環(huán)截面在承受內(nèi)部或外部徑向壓力時，受力較均勻 ，因此，絕大多數(shù)鋼管是圓管。用鋼管制造環(huán)形零件，可提高材料利用率，簡化制造工序，節(jié)約材料和加工工時，如滾動軸承套圈、千斤頂套等，當(dāng)前已廣泛用鋼管來制造。分為10#無縫鋼管、20#無縫鋼管、45#無縫鋼管等。材質(zhì)因素播報編輯（1）結(jié)構(gòu)的重要性 重型工業(yè)建筑結(jié)構(gòu)、大跨度結(jié)構(gòu)、高層或超高層的民用建筑結(jié)構(gòu)或構(gòu)筑物等重要結(jié)構(gòu)，應(yīng)考慮選用質(zhì)量好的無縫鋼管，對一般工業(yè)與民用建筑結(jié)構(gòu)，可按工作性質(zhì)分別選用普通質(zhì)量的無縫鋼管。（2）荷載情況 直接承受動力荷載的結(jié)構(gòu)和強(qiáng)烈地震區(qū)的結(jié)構(gòu)，應(yīng)選用綜合性能好的無縫鋼管；一般承受靜力荷載的結(jié)構(gòu)則可選用價格較低的無縫鋼管。（3）連接方法 焊接過程會產(chǎn)生焊接變形、焊接應(yīng)力以及其他焊接缺陷，存在導(dǎo)致結(jié)構(gòu)產(chǎn)生裂縫或脆性斷裂的危險。因此，焊接結(jié)構(gòu)對材質(zhì)的要求應(yīng)嚴(yán)格一些。（4）結(jié)構(gòu)所處的溫度和環(huán)境，無縫鋼管處于低溫時容易冷脆，因此在低溫條件下工作的結(jié)構(gòu)，尤其是焊接結(jié)構(gòu)，應(yīng)選用具有良好抗低溫脆斷性能的鎮(zhèn)靜鋼。此外，露天結(jié)構(gòu)的太原無縫鋼管容易產(chǎn)生時效，有害介質(zhì)作用的無縫鋼管容易腐蝕、疲勞和斷裂，也應(yīng)加以區(qū)別地選擇不同材質(zhì)。（5）太無縫鋼管厚度，薄無縫鋼管輥軋次數(shù)多，軋制的壓縮比大，厚度大的無縫鋼管壓縮比小，所以厚度大的精密鋼管不但強(qiáng)度較小，而且塑性、沖擊韌性和焊接性能也較差。因此，厚度大的焊接結(jié)構(gòu)應(yīng)采用材質(zhì)較好的無縫鋼管。標(biāo)準(zhǔn)播報編輯碳素鋼無縫鋼管有以下幾種標(biāo)準(zhǔn)：GB8163《流體輸送用無縫鋼管》、GB6479《化肥設(shè)備用高壓無縫鋼管》、GB9948《石油裂化用無縫鋼管》、GB3087《低中壓鍋爐用無縫鋼管》、GB5310《高壓鍋爐用無縫鋼管》。新手上路成長任務(wù)編輯入門編輯規(guī)則本人編輯我有疑問內(nèi)容質(zhì)疑在線客服官方貼吧意見反饋投訴建議舉報不良信息未通過詞條申訴投訴侵權(quán)信息封禁查詢與解封?2025?Baidu?使用百度前必讀?|?百科協(xié)議?|?隱私政策?|?百度百科合作平臺?|?京ICP證030173號?京公網(wǎng)安備11000002000001號window.PAGE_DATA=
